Z Dimension greater than 2,575 mm and
up to 3,000 mm. Three extension duct
kits required.
Z Dimension greater than 3,000 mm.
NOT PERMITTED.
– If no extension ducts are required, pro-
cede to 3.5.2.
– If an extension duct or ducts is/are to be
used, the flue and air ducts should be
joined before proceeding to the next sec-
tion. The extension ducts should be joined
to each other and to the standard ducts
using the following procedure (fig. 7):
– For the flue ducts in turn, push the plain
end of the standard and (if using two or
three extensions) extension duct into the
swaged end of the extension duct(s).
– Push an air duct in to the clamp. Join the air
ducts (larger ducts) and tighten the screws
an the clamp to connect them.
3.3.2 Cutting the flue/air duct
to the correct length
Rear flue outlet (fig. 8)
– Select the air duct (larger duct) and
starting at the formed end, ‘mark off’ the
length to be cut which is the wall thick-
ness X + 165 mm (6 1/2 in).
Side flue outlet (fig. 8)
– Select the air duct (larger duct) and start-
ing at the formed end, ‘mark off’ the length
to be cut which is the wall thickness X + the
clearance Y plus 155 mm (6 1/8 in).
3.4 CHARACTERISTICS OF FEEDWATER
IT IS ABSOLUTELY ESSENTIAL THAT THE
WATER FOR THE CENTRAL HEATING SYSTEM
IS TO BE TREATED IN THE FOLLOWING CASES:
– Very extensive system (with high con-
tents of feedwater).
– Frequent addition of makeup water into
the system.
– Should it be necessary to empty the sys-
tem either partially or totally.
3.5 SYSTEM FILLING
The filling of the boiler and the system is
done by the filling cock located on the bot-
tom of the boiler (fig. 9). The filling pressure
of the system cold must be 1 bar .
Once the filling has been completed, close
the filling cock.
3.6 HOW TO FIT C.H. AND D.H.W.
